Papules are small, raised bumps on the skin that can vary in color, size, and texture. They are typically less than 1 centimeter in diameter and can be caused by various conditions, including acne, eczema, or psoriasis. Papules may feel firm to the touch and can appear alone or in clusters. These skin lesions are often a sign of inflammation or irritation and may be itchy or painful. While papules are usually harmless, they can sometimes indicate an underlying skin condition that may require treatment. It's important to consult a healthcare professional for proper diagnosis and management.
